I'm afraid I only understand you a little, sorry... Electrolyte equilibrium? Crenation? ... =S
I dont suppose you know, but I've only just started my second year of Biology =( I dont know, well, too much

Um, you know chemistry don't you? what I mean by equilibrium here is like a reversible reaction in chemistry...
just imagine that in the left side is cell and in the right side is insterestisiil humour...

Q: Why are chemists great for solving problems?
A: They have all the solutions.
